Smart glasses use experience of nursing graduate students: qualitative study

Background Immersive technologies such as smart glasses can benefit nursing training and clinical practice. In this paper, we explore the views of nursing graduate students about their experience with smart glasses. Methods Nursing graduate students (n = 13) were recruited using purposeful sampling. First, a virtual reality intervention for hyperglycemia in nursing care was shown. This was an attempt to introduce people to the technology and start discussions about how it might be used in nursing care. After that, participants underwent online interviews. Thematic analysis was used to examine the data. Results The study findings indicated that the use of smart glasses as an enjoyable learning experience and immersive games positively affects nursing students. In addition, it was determined that they had negative experiences such as costs, lack of infrastructure, and smart glass side effects. Conclusions Smart glasses indicate good usability and availability in nursing education and potential for use in hospital nursing practice.

and virtual reality (VR) technologies, have opened the door to new pedagogical approaches in education [1].
The "Future of Nursing 2020-2030" report highlights nine recommendations critical to transforming nursing education in the modern world.These recommendations include considering access to virtual learning and simulations for students, indicating that educators and teachers should pay special attention to students from diverse backgrounds.Technological developments have enabled the increasing use of wearable technologies, especially in nursing education practices [2][3][4].While tools such as smart glasses allow students to improve their independent learning abilities, they also help students master each skill based on their current knowledge [5,6].
The advantages of using smart glasses include simulations of procedures such as blood transfusion, intradermal injection, and the Leopold Manouver.Students described the simulations carried out thanks to these

Background
Smart glasses in healthcare, especially in nursing education, are essential at the intersection of technology and educational practice.These innovative tools are critical for translating theoretical knowledge into practice by providing nursing students with realistic simulations and interactive learning experiences.This transformation, which started with the first Google Glasses released in 2014, indicates how technology can change daily life.Smart glasses, combined with augmented reality (AR) technologies as realistic and valuable, increasing their learning motivation and quality of education.For example, anaphylaxis scenario simulation using holographic video enriches learning experiences by allowing students to practice in a safe and interactive environment [3,4,7,8].
However, there are also difficulties associated with using smart glasses, such as technological problems and the need to perceive realism in the virtual world.These technologies require regular maintenance and updates and can sometimes result in students encountering simulations that are not as interactive as real-life situations [8,9].However, studies conducted in recent years show that overcoming such difficulties is possible with the development of technology [10].
The pedagogical use of smart glasses is of increasing interest because of how they can improve students' learning processes [11].Pedagogy requires a framework for structuring experiences that help students create and transfer knowledge.Pedagogical frameworks for how educators and researchers can effectively integrate these technologies to enrich learning and teaching processes are essential for developing models.No single theoretical model is dominant, especially in studies conducted using various digital platforms; instead, approaches exist that use more than one pedagogical theory [12].There is increasing interest in using virtual reality technologies as pedagogical tools, and research on the contributions of these technologies to the learning process emphasizes the importance of pedagogical approaches.However, there is insufficient evidence on applying pedagogical models to the design and use of virtual learning environments.More research is needed on the feasibility and effectiveness of integrating virtual reality technologies into nursing education [9].Evidence regarding the feasibility of incorporating this innovative learning and teaching technology into nursing education is lacking.Therefore, before its full-scale integration into the curriculum as a learning, teaching, formative and summative assessment tool, the usability of virtual glass simulation must be investigated, considering the application context.In this context, the study aims to enrich educational practice and improve student learning experiences by providing insights into how smart glasses technologies can be used more effectively in nursing education.
In this study, the students' views on the smart glasses experience were examined in depth, and the data on the students' smart glasses experience were collected using the semi structured interview form.In this study, smart glasses technologies enabled students to better perceive the findings by allowing them to experience some nursing practices independently.

Study design
This study employed a thematic analysis method as described by Braun & Clarke [13].Postgraduate nursing students are clinical nurses and are also pursuing master's and doctoral education.For this reason, their opinions on the use of smart glasses are important both in terms of education and in the clinic.This research was carried out qualitatively to determine the views of nursing graduate students about their experience with smart glasses.The Consolidated Criteria for Reporting Qualitative Research (COREQ), a suggested reporting system, was used to record the study results [14].

Study setting
The study was conducted at Hacettepe University of Nursing Faculty, which is situated in Ankara city in the southern region of Turkey.The faculty has 20 students enrolled in internal medicine nursing education.The smart glasses experience was carried out in faculty classrooms with the participation of a researcher.The researcher introduced the smart glasses to each participant, provided them with information about how to use them, and checked for possible side effects.Other researchers interviewed participants online using Zoom after the experience.

Study participants and sampling
The inclusion and exclusion criteria for this study were as follows:

Inclusion criteria
• Pursuing postgraduate studies.
• At least 1 year of nurse experience.

Exclusion criteria
• Newly graduated nurses.
• Not having a postgraduate degree or just starting.
The researcher contacted and utilized a face-to-face technique to tell 20 nursing students about the study and the participant inclusion criteria before selecting study participants for sampling.Only 13 of the potential participants responded to the researcher's inquiry and met the study's inclusion requirements.

Design and development of the game
The treatment of hyperglycemia and nursing care provided by smart glasses are the main topics of this section's summary of our diabetic patient game.The game's design is unique and specifically tailored to its intended nursing audience.Two nursing experts helped to develop hyperglycemia treatment.Based on the game's concept and layout, the colors, text font, and visual identities of the screen elements were created, creating a harmonious composition appropriate for "generation Z".Wearing smart glasses allowed players to participate in the game's experiential environment.
• The video game was created using Oculus Quest and Unity 2020.3.3f1 to run on a variety of immersive virtual reality platforms.This game is an extension of earlier projects by Calik et al.The primary goal of earlier incarnations of the project game was to assist with hyperglycemia therapy and nursing care.
It talks about helping the nurse care for a patient and orienting the student nurse on their first day at the hospital.• The Unity Game Engine was used for this project because it makes it simple to create cross-platform video games that can be played on a variety of platforms, including Windows, Mac, Linux, Android, and iOS.Games made in Unity can be smoothly integrated with VR headsets.The accessibility of the game was considered during the design.Head movement is required to play the entire game.The player moves in accordance with the movements of a headset and an object mounted on the Unity XR Rig.
The main technical difficulty with VR in the literature relates to using hand controllers to navigate the virtual environment.Therefore, we researched a video game, and the participants did not use the controllers (Figs. 1, 2, 3, 4, 5 and 6).

Surveys and questionnaire
When the participants came to the venue, they were first given a sociodemographic characteristics questionnaire consisting of ten questions, which included personal information and previous experiences of the students (Table 1).Afterwards, in-depth interviews were conducted with the participants using the Semi-Structured Interview Form consisting of seven questions.The participants' opinions about their experiences with the video game using augmented reality technology were determined.

Data analysis
According to Braun and Clarke's theme analysis [13], the data were manually evaluated.The process of data analysis was developed step by step.Within 48 h after data collection, interviews were recorded on a digital voice recorder and then verbatim transcribed.The concepts and codes that overlapped or were similar were compared and debated by the two researchers as a second phase before being combined to create categories.A third researcher analyzed the first classifications and the quotes that accompanied them (S.K.).The aim was to limit the risk of missing relevant units in the condensation process.Finally, the researchers discussed the results, and a consensus was reached on descriptions of the experiences represented by the extracted meaning units.

Discussion
This study explored graduate nursing students' views of using smart glasses in nursing healthcare following a brief intervention to promote nursing care in hyperglycemia treatment.Participants generally strongly emphasized the novelty, ease of use, and enjoyable learning experience of smart glasses.
In our study, we selected nursing students enrolled in a graduate program.Our aim in selecting the sample was that we thought that nurses with clinical experience would add a different perspective to the use of virtual glasses.We also thought that they would bring more suggestions and comments regarding the aspects that could be useful and improved in hospital education and postgraduate education, and indeed, they did.We had participants who felt better because the environment they experienced was different from the hospital environment or because they did not find it realistic in terms of design.According to the literature, the opinions of students who have more clinical experience than undergraduate students are more meaningful [8], and doing so in small groups, such as graduate students instead of crowded undergraduate students, is more effective with virtual glasses.associated it with having experience [15].
Interactive, immersive environments such as AR, VR and XR have generally created positive emotions in users.Participants generally emphasized the novelty, ease of use, and enjoyable learning experience of XRs.In one study, users experienced more positive emotions than in computer-based simulations [16].Another study stated that nursing students showed great interest in their smart glasses experience and were encouraged to reduce their anxiety [17].Although the immersive nature of smart glasses enhances experiences in many contexts, participants said that they feel worried and anxious.We attribute this to the fact that smart glasses technology is new, and the participants need to gain more knowledge of this technology.
Smart glass technology is a rich, interactive, and engaging educational strategy supporting experiential learning [18].In our study, participants emphasized their experience as an immersive, fun learning experience.In previous studies, students stated that using smart glasses technology to view 3D structures seems more motivating and exciting than traditional methods such as books [19,20].An opposing view stated that the immersive experience of being in a simulated reality overshadowed the acquisition of cognitive skills.For example, Moesgaard et al. (2015) described this as the place where study participants reported that they were "too fascinated by the [virtual] environment to notice the information presented to them." [21].Even though one participant in our study found the environment he was experiencing gripping, the statement, "When I turned my head to a different place, the information continued to come in visual and written information, and this helped me to break away from the flow, " showed that it was immersive and focused on the game.In addition, the participants stated that adapting to smart glasses technology is comfortable.In this case, it can be associated with the fact that we did not include any interaction area in the game.Because smart glasses technologies are costly in Turkey, this study does not receive financial support.However, given the rapid development in the field, we expect the smart glass hardware landscape in our country to change quickly.
Motion sickness and nausea are drawbacks of smart glasses [22].We asked whether motion sickness and nausea are caused by novices' attempts to become accustomed to the technology or whether they linger over time and can potentially impair learning or education.A few participants in our survey claimed to wear glasses and suffer from environmental sickness.consequences may vary depending on how real-world and virtual surroundings are combined in AR devices, but this should lessen negative health consequences, including dizziness and blurred vision, in VR applications [23].
The usage of the content created for trainers is challenging due to the high cost of smart glasses technology [22].The participants acknowledged the advantages of these technologies but claimed that because of their high cost, accessing them was challenging.Its usage for independent study at home is hindered by high costs, such as the price of the virtual dissection table.Due to economies of scale, some technologies may be able to lower costs [24].Although these technologies have received excellent review, it is still unclear who will be responsible for paying these expenses.Therefore, when utilizing these technologies, cost-effectiveness should be considered.
The use of smart glasses in nursing care was suggested by the participants to enhance patient care and treatment.Since the idea of utilizing immersive technology in nursing education has still been relatively undeveloped, it was simpler for researchers to develop new concepts, introduce improvements, and make contributions to the profession.Many academics are interested in the concepts, features, technical principles, tools, application scenarios in various sectors, existing issues, and prospects of smart glasses technology.With the integration, in-depth interaction, and coexistence of various temporal and spatial objects, smart glasses are now being incorporated into the educational sector [25].In addition to skill areas such as classroom nursing education, clinical nursing, intensive care nursing, and intravenous procedures, this approach has obvious technical advantages in the orientation process of new nurses and has unlimited potential development and application areas.
While respondents generally described smart glasses as a fun visual design, they found the technology suitable for younger demographic information and too mobile for middle-aged adults.Technology use, exposure, and unfamiliarity can affect opinions about design [25].In addition, the personal differences of individuals in the learning environment can distinguish design evaluations in the experience environment, which is quite normal.

Limitations
The reason for this was that the game developed for smart glasses was about diabetes.Therefore, a purposive sample was used, and students enrolled in the internal medicine nursing graduate programme were included in the study.

Conclusion
In the education of nursing graduates, there are great opportunities for the use of smart glasses.Smart glasses games can play a supportive role in the transfer of graduate knowledge and skills to the clinical environment and education.
These results showed that the nurses working in the clinic had no difficulties using smart glasses and even enjoyed the experience, even though they were not very familiar with the technology used in education.They interpreted the smart glasses as an opportunity to practice nursing processes and skills in a variety of settings.For example, for nurses starting out in the clinic, working in intensive care, and in nursing education.There is a need to integrate smart glasses into the training of nurse educators and hospital administrators.
